LOCK FOR MAIL-POUCHES.

SPECIFICATION forming part of Letters Patent No. 298,451, dated May 13, 1884.

Application tiled December 12, 1883.

To @ZZ whom t may concern,.-

Be it known that I, Gns'mvn DEIMEL, of Hancock, in the county of Houghton and State of Michigan, have invented new and useful Improvements in Locks for Mail-Pouches; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvementsin inail-pouch locks, and is especially designed as an improvement upon Patent N o. 229,356', dated June 29, 1880, Patent No. 184,087, dated November 7, 1876, and Patent No. 238,127, dated February 22, 1881.

The invention consists in a peculiar conas` more fully hereinafter described.

Figure 1 is a perspective view of the upper section of a mail-pouch, the upper end and frame of which are constructed as described in Patent No. 238,127, and showsthe front of an improved lock. Fig. 2 is a plan of such lock with the front thereof removed and shown in reverse. Fig. 3 is a cross-section on the line .fr x in Fig. 1.

In the accompanying drawings, which form a part of this specification, A represents the upper end of the bag, which is rigidly secured to a metallic frame, such asis described in the last hereinbefore mentioned patent, such frame being provided with notched studs A,proj ecting inwardly, as described in said Letters Patent, and for a like purpose.

B is a plate rigidly secured to the front of the flap C of the bag, and it is provided with an irregularly-shaped chamber, a, to inclose the operating parts of the lock. This plate is provided with a sliding lock plate or bolt, D, in which the slots b inclose the springs c, designed and arranged to compel such lock-plate to engage with the notches upon the studs A', except when forcibly disengaged, as hereinafter described, by the operation of the key.

E is a pawl pivoted to the lock-bolt D, and F is a spring to compel such pawl to remain out of the path of the rotation of the key-spia dle G and its tooth H, except as hereinafter described. VThis spindle G projects through the front plate of the lock I, and is operated by the key J.

(No model.)

Upon the front of the plate I there is secured a sliding plate, K. By mea-ns of studs d, passing through said plate and into slots in the plate I, the movement of the plateK laterally is limited, and between the plates K and I is a spring, L, so arranged as to lock the two plates together, except when the projecting end of the spring` is forced out of engagement with the plate K. A stud, e, rigidly secured to the rear side of the plate K,passes through a slot, f, in the plate I, where it engages with the spring g, which spring compels the plate K to resume its normal position after the pressure which has moved it to one side has been released. Leaving this plate K to one side after disengaging the spring L brings the stud e into contact with the spring-pawl E, and forces the same backward against the action of the spring F, and holds the end of said pawl in the path ofthe stud or arm H, which projects from the spindle G, so that when the key is turned in the proper direction the lock plate or bolt D is moved laterally until it disengages from the notched studs A, and allows the pouch to be opened.

The slide-plate K is so constructed as to receive and contain a card upon which the postoftlce to which said pouch is designed to go is exposed.

I am aware that padlocks have heretofore been constructed with a sliding plate carrying a pin designed to engage with a pawl pivoted to the locking-bolt, and bring the same within range of the locking device, and so do not claim such, broadly, as forming a part of my invention.

Vhat I claim as my invention is 1. In a locking device, and in combination with the spring locking-plate D and springpawl E thereof, the sliding plate K, provided with the pin e, to engage the pawl E, substantially as and for the purpose set forth.

2. In combination withthe notched studs A,fastened to the frame of a pouch, and constructed to pass through the iiap of the same and into the plate B, secured to said flap, the locking spring-bolt D, secured to said plate and engaging said studs A', and provided with the spring-pawl E, the sliding plate K, secured on the face of said lock, and carrying the pin @,constrncted to come in contact with said pawl and bring it within the path of the IOO front of said look, whereby the said plate serves the double purpose of displaying an address and of throwing said looking mechanism into a fixed position to be operated on by the tooth of the key-spindle7 substantially as described.l
